Which microphone type is commonly used for interviews and small video productions due to its discreet size?

The lavalier microphone is a popular choice for interviews and small video productions because of its compact and discreet design. These microphones are typically small, clip onto clothing, and can be positioned near the speaker's mouth without being obtrusive, allowing for clear audio capture while keeping the focus on the subject. This is particularly valuable in interview scenarios where a more visible microphone could distract from the conversation or the visual composition of the scene.

In contrast, a shotgun microphone is designed to capture sound from a specific direction and is often used in situations where the microphone needs to be positioned some distance from the subject, which can be less convenient for handheld interviews. A cardioid microphone is characterized by its directional pickup pattern, which focuses on sound from the front while rejecting sound from the sides and back, making it less discreet than a lavalier. A dynamic microphone is typically larger and often used in live sound settings or for capturing loud sources, making it less suitable for discreet recording applications such as interviews.
